   Ensure that www.usatoday.com is not listed there. If it is, remove it.

2. Block the Website Completely

If you want to block the website entirely, you can do so by using the built-in features of Firefox or by using an extension: Method 1: Block the Site in Firefox

   Open Firefox and type about:preferences#privacy in the address bar.
   Scroll down to the "Permissions" section.
   Click on "Settings..." next to "Notifications."
   If you want to block the site from sending notifications, you can also add it to the "Block" list if you see an option for it.

Method 2: Use a Block Site Extension

You can use an extension to block specific websites:

   Go to the Firefox Add-ons page: Firefox Add-ons
   Search for a site-blocking extension, such as "Block Site" or "uBlock Origin."
   Install the extension and follow the instructions to block www.usatoday.com.

3. Clear Cookies and Cache

If you want to ensure that any previous permissions or settings are cleared, you can also clear cookies and cache:

   Click on the menu button and select "Settings."
   In the left sidebar, click on "Privacy & Security."
   Scroll down to the "Cookies and Site Data" section and click on "Clear Data..."
   Select both options and click "Clear."

4. Check for Extensions

If you suspect that you might have an extension related to USA Today that you don’t remember installing:

   Click on the menu button and select "Add-ons and Themes."
   Go to the "Extensions" tab and look for any extensions related to USA Today or that you don’t recognize.
   Disable or remove any suspicious extensions.

5. Reset Firefox (if necessary)

If you continue to have issues and want to start fresh, you can reset Firefox:

   Click on the menu button and select "Help."
   Choose "More Troubleshooting Information."

I found it troubling that the {windows side) notification pop up would trigger a new tab , when clearly clicking the "disable notifications" option there.

Problem appears to be solved using your instruction. Thank you very much.
